Specification of Letters Patent.

Application filed May 18, 191 6. Serial No. 98,306.

To all whom it may concern:

Be it known that I, HENRY B. COOLEY, a citizen of the United States, and a resident of Kensington, in the county of Hartford and State of Connecticut, have invented a new andImproved Feeding Mechanism for Fastener-Setting Machines, of which the following is a specification.

My invention relates more especially to machines for affixing fastening devices to envelops and by means of which the envelops are temporarily secured to close the openings to the flaps, and an object of my invention, among others, is to provide a machine of this class that shall be simple in construction and in its method of operation and particularly efficient as to the character of work performed thereby.

One form of machine embodying my invention and-in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawings, in which- Figure 1 is a view in front elevation of a portion of a machine embodying my invention with parts broken away to show construction. j

Fig. 7 is adetail view looking toward the face of the chute for the rivets.

Fig. 8 is a detail side view of the upper part of the chute and lower part of the rivet guide.

The, invention forming the subject matter of this application relatestothe machine illustrated and described. in my c0- ending application of Serial Number 46, 798 filed February 7tl1,1913, the present ward into position to invention relating to the riveting mechanism of said machine, and for this reason part of'the mechanism of said machine not constituing a direct part of said riveting mechanism is omitted from the drawings herein and reference is hereby made to the patent to be issued on said copending application for a disclosure of such parts of the machine as are not shown herein.

In the accompanying drawings the numeral 1O denotes legs supporting a bed 11 of the machine, which parts are of any suitable material secured together in any desired manner. A driving pulley 12 supported on a driving shaft at the rear of the machine is adapted to receive a belt driven from any suitable source of power and the pulley may have anygdesired mechanism for securing it in or detaching it from driving connection with the shaft, the mechanism for operating this connection including a starting and stopping pin 13, and an operating lever 14: pivotally supported by the bed on a bar projecting therefrom and pivotally connected at one end with said starting and stopping pin and at its other end with an actuating rod 15 connected with a treadle 16 arranged to be actuated by the feet of the operator of the machine, a spring 17 secured at its upper end to the rod and at its lower end to the treadle pulling the rod normally downward and causing the pin 13 to be normally held in position to disengage said pulley from the driving shaft, and as more particularly shown in my said copending application. When the treadle is pressed downward upward movement of the rod 15 moves the pin 13 downermit operation of the parts to connect t e pulley with the driving shaft. The driving shaft is con- 1 nected in any suitable manner at its opposite ends to rotate cross shafts 18 and 19 I mounted in hearings on the bed 11. A supporting slide 20 is mounted for reciprocating movement in a slideway 21 in the bed 11, the slide being held in place in any suitable manner as by dove-tailed projections 25 engaging similarly shaped grooves 26 in the slideway. This slide has a supporting plunger. 22 rigidly secured. thereto at one side anda cap 23 secured to the slide has an actuating rod 24 pivotally attached to the cap and connected with an eceentriefl? se Patented Feb. 18, 1919. i

. 44 against which the rivets are held bythe ingbeyond .the end of the plunger 30. This punch is tubular and contains a rivet supporting pin 32 having ahead 33 to retain it in place, a spring 34 being located in the recess behind said pin and thrusting against it to force it normally outward.

A cap 35 secured to the riveting slide 28 has a slide actuating rod 36 pivotally se cured thereto, said rod being connected with an eccentric 37 secured to the cross shaft 1 9, by means of which eccentric the slide 28 is reciprocated. An adjusting screw 38 is mounted in the cap 35 and serves as a backstop to properly locate the plunger 30. A

rest 39 is located in an envelop receiving opening 40 in the bed of the machine upon which rest the envelops are placed on edge, and a supporting shoe 41 is secured atone end to a block .42 located in the slideway 29 and secured to the bed, the end of the shoe being pointed and extending along the open ing 40, as clearly shown in Fig. .2, in position to project into an envelop, theend of the flap of which rests against an enitelop stop 43 to be hereinafterdescribed. A die punch "31 is secured to theshoe andnn envelop guide 45, in the form of a spring. isv

secured at one end to the shoe and projects to guide the envelop over the die 44 when the former is placed on the shoe, the guide yielding and its free endmoving toward the shoe when the rivetingtakes place.

A supporting bar 46 i secured to the legs 10 at the front of the machine and extends thereacross from side to side, :a rest support 47 projecting upwardly from said bar at about its center and having the envelop stop 43that is adjustably supported on the bed 11, located over or resting against itsupper end. A dove-tailed shaped rest guide 48 is secured to the rest support, the end of the rest 39 having a dove-tailed shaped groove to engage said guide as shown in Fig. 2 of the drawings, this groove extending into a base 49 of the rest, which base is provided with a set screw (see Fig. 1) by means of which the rest may be detacl ably secured in any desired position.

A post 50 rises from the'bed 11, this post being curved forwardly at its upper end to locate a holder disk 51 rotatably supported at 1ts upper end over a rivet feed for supplying rivets to the mechanism. A holder 52 is secured to the disk 51, this holder being in the form of a wire upon which the rivets 53 are placed, these rivets beingof aform commonly used on envelope and each having a central tubular portion 54 with flexible arms 55, as shown in Fig; 4, which arms are adapted to be passed through an opening in the flap of an envelop and then bent backwardly to hold the flap of the envelop in place. A guide 56 of'trough shape to receive the rivet arms on one side of the tubular portions of the rivets located on the holder 52, is'secured to or forms part of the cover for a rivet chute hereinafter described. The disk 51 may be rotated as by means of a handle 57v to place the holder in a position diametrically opposite to that shown in Fig. 1, in which position the holder may be loaded and after which, and before it is placed in position to feed an aliner 58, pivotally mounted on one side of-the post 50, is employed, when swung into an upward position (see Fig. 6), to aline the rivet arms so that they will be properly located in the guide 56 when. the holder is rotated to the feed position shown .inFig. 1. hen not in use to aline rivets the alinermay be swung downwardly against the back of one of the flanges on the post 50. This aliner consistsof an arm having a grooveto receive the arms of the rivets, which aliner .nm 15 pivotally mounted on the post, as clearly shown in F ig.: 6, it being of a length to engage all :ofthe rivets on the holder when swung upwardly from its position of rest which is a position at right angles to the position shown in Fig. 6.

A bracket 59 is secured to the front ofthe bed, rising therefrom to support a rivet feed wheel 60 rotatably supported in branches 61.. This feed wheel v has feed pins 62 projecting therefrom and a ratchet 63 is secured to the shaft of said wheel, preferably underneath the branches to .rtate it. A pawl arm 64 is rotatably mounted on the shaft of feed wheel and bears a pawl 65 adapted toengage the teeth of the ratchet. A ratchet rotating barfifi is adjustably secured to a support 67 risingfrom the rivet slide28, the ratchet being. thus operated at each reciprocatingv movementv of said slide.

A chute 68 is secured to the block .42., rising. upwardly therefrom and curved to This chute has agroove 69. which isclosed by a cover 70 secured toithe .side .pantsof the chute, in theconstrnction herein shown the guide -56 being. secured to the chute above the cover. The feed wheel 60 projects through. one side of thegroove .69, the flexible arms. ofthe rivets 55 resting upon a side part at the upper end of the chute 618 and upon the feed wheel. In each reciprocating movement of the slide 28 the feed wheel is given a one step rotation, causing a pin thereon to strike an arm of the lower-most rivet, imparting to. the rivet a quarter turn and alining the arms with the groove 69 in the chute. As soon as the arms are thus alined the lowermost rivet drops onto the inclined bottom of the groove and falls to a position in front of a hole 71 in the chute 68 in which position it is held by a rivet rest 72 in position to receive the rivet punch 31.

The lower part of the runway or groove 69 is closed by agate 73 mounted on a latch 74: pivotally supported on the bracket 42 and having a cam 7 5 located in the path of movement of the end of the plunger 30. This gate has an opening 77 in its edge to receive the hollow hub of the rivets, and the cam 75 is so formed that as the riveting plunger 30 moves forward it operates to move the gate backward at the proper time from in front of the rivet that is thus allowed to be carried by the pin 32 against the die 44, a spring 76 returning the latch to its normal position as shown in Fig. 4, this spring being attached to a pin 78 on the latch.

The lower end of the guide 56 is oifset to form a separating slot 80 between this offset portion and the upper edge of the chute 68 as clearly shown in Fig. 3 of the drawings. As the rivet is turned from the position shown in Fig. 4, by the wheel 60, one arm of the rivet passes into the separating slot and the rivet, when the wheel 60 has alined it with the groove 69, separates from the stack and falls onto the sloping surface of said groove, and into the position as shown in dotted lines in Fig. 3 of the drawmgs.
